Question

what is one stated purpose of the world trade organization?
to monitor trade policies of many countries
to create a common currency
to establish direct trade agreements between countries
to encourage the expansion of exports

Explanation:

The World Trade Organization (WTO) has the purpose of encouraging the expansion of exports (among other trade - related goals). Creating a common currency is for the European Union (e.g., Euro), establishing direct trade agreements between countries is more of a bilateral or regional trade deal aspect, and monitoring trade policies is part of its work but the option “to encourage the expansion of exports” aligns with its goal of facilitating and promoting international trade which includes export expansion.

Answer:

to encourage the expansion of exports
